Description

Technical Field

[0001] The utility model belongs to the technical field of cement grinding equipment, and in particular relates to a feeding device for a roller press with a double-layer structure and a dense material bed. Background Art

[0002] Roller presses are common equipment in cement grinding, and the feeder they use plays a crucial role in system energy efficiency. Common feeders include linear reciprocating plate-type, lever-swing flap-type, and hyperbolic swing-type composite structures.

[0003] Existing linear reciprocating insert plate feeding devices adopt manual insert plates or electric and hydraulic push rods with automatic adjustment of center unloading on both sides. The throughput of the roller press is adjusted by adjusting the depth of the insert plates inserted into the chute, changing the cross-sectional area of ​​the unloading pipe and the material receiving area of ​​the roller surface. However, when the insert plates are half-open or fully-open, the tangential space around the roller press is large and the material bed is loose, which will cause the material bed to lose pressure, the work of the roller press to be lost and the roller surface wear of the roller press to be accelerated. The axial end face of the roller press will also leak material, resulting in serious wear of the side baffle. Summary of the Invention

[0011] Furthermore, the servo motor is used to synchronize with the roller press to drive the material guide slide to move back and forth in a straight line, and automatically adjust the opening and closing size to control the feed amount, thereby automatically preventing material blockage.

[0012] Furthermore, a detachably connected material guiding wear-resistant plate is provided on the surface of the material guiding slide.

[0013] The beneficial effects of the present invention are:

The main body bracket 1 is provided with a feed port 12. The main body bracket 1 is also symmetrically provided with two inclined material guide brackets 3. The top of the material guide bracket 3 is provided with a driving device 2, and the output end of the driving device 2 is also connected to a connecting rod 4.

[0026] Four guide rails 8 are arranged in parallel on the material guide bracket 3, and four pairs of sliders 7 corresponding to the guide rails 8 are arranged on the bottom surface of the material guide slide 5. The material guide slide 5 is slidingly connected to the material guide bracket 3 through the sliders 7 and the guide rails 8. The material guide slide 5 is also fixedly connected to the connecting rod 4, and the material guide slide 5 is controlled by the driving device 2 to perform reciprocating linear motion on the material guide bracket 3.

[0027] In this embodiment, the driving device 2 includes a piston electric cylinder, a reducer, and a servo motor connected to the piston electric cylinder through the reducer. By using two servo motors to control the reciprocating linear motion of the two material guide slides, the linkage synchronization with the roller press is strong, the opening size can be accurately adjusted and the feed amount can be accurately controlled, thereby automatically adjusting the feed amount to prevent blockage.

[0028] Furthermore, the surface of the material guiding slide plate 5 is also provided with a detachable and replaceable material guiding wear-resistant plate 6.

[0029] The lower end of the main frame 1 is provided with a discharge port, which includes a circumferentially arranged tangential baffle 10 and a side baffle 11. The bottom of the tangential baffle 10 and the side baffle 11 is an arc-shaped plate that fits the roller of the roller press and maintains a gap of 15-20mm with the roller circumference, forming a dense pressure maintenance and improving the working efficiency of the roller press.

[0030] The pressure-maintaining extension plates 9 provided on the two material guide slides 5 and the circumferentially arranged tangential baffles 10 and side baffles 11 form a double-V-shaped double-layer sealing structure, which greatly improves the sealing performance, ensures balanced discharge of the material outlet, and prevents the occurrence of material bed pressure loss and roller deviation.

[0031] Working principle:

[0032] The material enters from the feed port 12, and the driving device 2 controls the reciprocating linear motion of the guide slide 5 to accurately adjust the opening size and control the feed amount. It is automatically adjusted synchronously with the roller press to prevent blockage.

[0033] During the operation, a pressure-maintaining extension plate 9 extending into the discharge port and a tangential baffle 10 and a side baffle 11 that maintain a 15-20mm gap with the roller body are provided on the material guide slide 5 to achieve double sealing and pressure maintenance to ensure a dense material bed and prevent the material from leaking into the end face of the side baffle 11 and rubbing against it during operation. At the same time, the work loss of the roller press is reduced and the work efficiency is improved, thereby achieving the effects of stable production, gain, energy saving and consumption reduction.
